How long does a person stay at a museum? A couple of hours? There are people who would want exhibits at a museum to have a whole lesson plan so you can poll people and ask them “What did you learn?” Then you’d judge the success of the exhibit based on how well people do on these exams.
I have a different view. The person is going to spend incalculably more time in a classroom than they ever will in a museum. So a museum shouldn’t be a supplement to a classroom. It should be a force to ignite flames within a person’s soul of curiosity. An exhibit should make a person say “Wow! I’ve got to find out more about this!” and trigger them to explore more advanced accountings of the topic, in books or science videos. Once the flame is lit, the learning becomes self-motivating. — (from “Why The New Cosmos Matters“)
